Engine oil LIQUI MOLY or AMSOIL

Also my main purpose is for wear protection and high temp protection etc which the regular line does exceptionally well

I use liquimoly leichtlauf 5w-40. Bit of advice: these are VERY easy to overfill if you're not careful, so refill slowly. Put in less than you think you need, once it registers on the oil level sensor, then start the car for a minute. After that, leave if for a few hours to drain before continuing to fill.

From wear ratings and certification Amsoil, Pennzoil Ultra Platinum, Mobil 1 (Extended Interval). Amsoil I only use for track days, since I swap the oil out at 3.5-4K.

amazon.ca has Liqui moly TOP TEC 6200 SAE0W-20, VW508 00/509 00. Been using this since day 1 on my 2021 Tiguan with no issue.

Real synthetic oil is way better than regular oil. Even full synthetic oil is better than regular oil. But if you want the best oil for the money look into Amsoil signature series. This oil is a true 100% synthetic oil and will prevent wear and quiet an engine down better than regular oil. I had a lifter tick in my Volvo 850 and it was caused by the pickup tube seal wearing away. I put Amsoil signature series in it and the film strength of the oil was so good it stopped ticking for a year before I had the seal replaced.

After 12 years and 45K miles. I took a 05 Mustang and added a supercharger. For the next three years , and 15K miles, I took it drag racing and high performance track day driving. Wanting more horsepower, I had the engine rebuilt with forged performance parts. When the engine builder measured the wear in the block, everything was still within factory specifications. I had used Amsoil for the life of the car.

I buy Liqui Moly 6200 from germanparts.ca for about $70/5L. Our Tiguan consumes a lot of oil sadly, so I buy a lot of it. My mechanic recently recommended using Liquid Moly 2331 (Leichtlauf) 5W40 to see if it helps with oil consumption, and have had that in for the last month or so.

Liqui Moly 0W-20 LR for my F-Type-R. Doesn't use much oil, so cost is somewhat irrelevant.

Had an E63 that I recently traded with almost 200K miles, a few months ago I scoped my 1 and 5 cylinders and they had what I would consider normal to no wear. So as a DIY'r, here are my observations, This is a bigger issue in the States than it is in Europe. ... Keeping the engine clean is key. Frequent oil changes no more than 5k mi, using quality oil and fleece filters, formerly a Mobil 1 guy, now using LiquiMoly.

Also going to switch from Motul to LiquiMoly and see if I can tell a difference.
